Abstract: A air elimination device for removing air or gas bubbles from aqueous liquids flowing through an intravenous delivery system.  The device comprises a housing having an interior chamber, an inlet passage, an outlet passage, and one or more vent openings.  The inlet passage delivers the liquid into the interior chamber.          The outlet passage delivers the liquid from the interior chamber.  A hydrophobic membrane is attached to the housing and positioned over the vent openings.  The hydrophobic membrane allows gas bubbles in the aqueous liquid that enter the interior chamber of the housing to pass through the vent openings while preventing the liquid from passing through the vent openings.  The outlet passage comprises a stem which extends inwardly into the interior chamber and terminates in an interior end.  The vent openings are shaped and located in the housing such that at least a portion of a vent opening will be positioned at a higher elevation than that of the interior end of the stem irrespective of the orientation of the housing.

Abstract: La présente invention concerne un démodulateur AMDC dont l'effet de suppression des interférences est amélioré même quand des signaux proviennent de nombreux dispositifs de communication. Le démodulateur reçoit des signaux envoyés par plusieurs dispositifs de communication et ayant une structure de trame dans laquelle un signal pilote ayant une forme connue est intercalé entre des signaux d'information à des intervalles de temps réguliers. Ce démodulateur comprend des dispositifs de suppression d'interférences qui démodulent les données émises à partir des dispositifs de communication, et évaluent les signaux d'interférence. Le démodulateur évalue la variation de chaque parcours des canaux, effectue la démodulation des données reçues et évalue la réplique du signal d'interférence, réplique dont les erreurs diminuent lorsque les données passent par les dispositifs de suppression d'interférences, ce qui produit un effet marqué de suppression des interférences. Quand la suppression des interférences est exécutée après la détection du niveau de réception de chaque canal dans la somme totale de la puissance électrique reçue des parcours des canaux et après la détermination des rangs des canaux dans l'ordre des niveaux de réception, un effet supplémentaire notable de suppression des interférences se manifeste.

Title: Noise canceling method and apparatus therefor
Inventor: IKEDA SHIGEJI
IPC: G10L21/0208
Filed: 1997-06-13
Abstract: In accordance with the present invention, for noise cancellation, a reference noise signal is input to signal-to-noise (SN) power ratio estimating circuitry via a reference signal input terminal. The SN power ratio estimating circuitry causes its adaptive filter for producing a pseudonoise signal from the reference noise signal to operate. The circuitry detects error signal power and pseudonoise signal power out of the pseudonoise signal and other signals, and then outputs an estimate of an SN power ratio based on the detected power. A first delay circuit is connected to the output terminal of the above circuitry. A comparator compares an estimate of an input to and an estimate of an output from the first delay circuit, and produces greater one of the two estimates as an expanded estimate. A step size output circuit controls, based on the expanded estimate, the step size of a second adaptive filter connected to the reference signal input terminal via a second delay circuit. A subtracter subtracts a pseudonoise signal output from the second adaptive filter from a received signal sequentially delayed by a third and a fourth delay circuit, thereby cancelling a background noise signal component contained in the received signal.

En jouant, le joueur fait adroitement avancer un jeton sélectif d'un certain nombre de cases selon le lancer du dé. Chaque case de la planche indique un opérateur arithmétique qui détermine quel jeu de cartes de questions choisir. Le joueur se sert des planches fractions et de la boîte à glisser pour essayer de déterminer visuellement la réponse à une question précise. Si le joueur donne la bonne réponse, son jeton reste sur la case sur laquelle il l'a placé à la suite du lancer du dé. Toutefois, si le joueur ne donne pas une bonne réponse, il doit replacer le jeton sur sa case d'origine. Le joueur en tête gagne la partie en faisant adroitement avancer son jeton sélectif jusqu'à la case supérieure de la planche à jeu multicases.

Title: Modified cells and methods for inhibiting xenograft rejection
Inventor: YATKO CHRISTOPHER
IPC: A61K35/12
Filed: 1996-04-19
Abstract: Improved methods for inhibiting rejection of transplanted cells in allogeneic or xenogeneic recipient subject are described. The methods involve altering at least one antigen on the surface of a donor cell prior to transplantation to reduce the immunogenicity of the cell in a recipient subject. Preferably, an MHC class I antigen on a donor cell is altered by contacting the cell with a molecule which binds to the antigen, such as an antibody or fragment or derivative thereof. The altered cell can then be transplanted into a recipient subject such that immune cell-mediated, e.g., T cell-mediated, NK cell-mediated, and/or LAK cell-mediated, rejection is inhibited.
